Missing poster images in newsletter

[Jandalslap]

I noticed that some poster image links in my newsletter emails were broken, and I think I’ve figured out why, though not exactly how. Seems to only effect movie posters due to upgrades.

It appears that when a movie is upgraded in Jellyfin (eg. replaced with a higher quality version), the old Items Id is removed and a new one is generated. This is expected Jellyfin behavior.

My question is: is the newsletter still using a previously cached Items Id from newsletter.db, which no longer exists in Jellyfin? Or is Jellyfin somehow mapping upgraded media to old cached metadata, making it appear unchanged in the UI, even though the underlying ID has changed?

Somewhere here lies the root of my problem I think. Please leave a comment if you have seen similar behavior or have any other ideas.

it's using the previously known image id. If a new one is added later, it won't get picked up (this is a feature i've been wanting to implement/fix but haven't gotten around to it lately.. Life's been busy)
